iChat Screen Sharing: Audio works but video is a white screen.

I am having a problem using iChat screen sharing with a specific computer. We are both running OS 10.7.4. I have a Mac Book Pro (fall 2011) and he has a iMac one to two years old. We have tried contacting apple support but no luck yet. We tried setting up a test user to see if the problem was user specific but encountered the same problem. Again, video and text chat work fine. He can share my screen with no issues. Only when I ask to share his screen do I get a blank white screen. Audio works and I can manipulate his curser but all I have is a white screen. I have tried changing the resolution on his iMac but this has not helped. Also we are both using Google Talk as the chat server.

Mac OS X (10.7.4)

Hi,

Whilst not Screen Sharing he should change his Screen Resolution to the same or less than yours.

This is a workaround.

A semi fix is to use Time Machine to backstep to before the Apple Remote Desktop 3.6.0 update in Lion

There is no fix from Apple yet.

Ralph,

I'm running into same problem. How will we know when this gets fixed? Should we be looking for an update to be pushed via Software Update or should we monitor a particular location/forum?

Thx.

Hi,

Historically iChat Updates came in OS updates.

Not every OS update had an iChat update but that was the way they were delivered.

Only twice during the lifetime of iChat 3 have there ever been standalone Updates outside of this.

Most Updates are now through the App Store but Software Update can still be used (I have mine set on Daily despite Apple's Updates normally coming on Tuesdays)

One person stated he thought there had been a change with OS 10.8.1 saying the Build number of Messages had changed.

In my experience it has not and when Apple do update something the build Number and Version number change.

It is widely know that Apple send Developers and others advance copies of the OS to try out.

Those people sign NDAs (Non Disclosure Agreements) so you will not see any discussion of any up and coming stuff on this site.
